MALIIGAZA STEP-E4 Tuya WiFi Smart Motion Sensor Stair Light Kit - Plug & Play 24V COB LED Strips with Main Line Cable 5-30 Steps (High CRI 90+, Simultaneous Illumination)

Smart Stair Lighting Without Complicated Wiring

Upgrade your staircase with the MALIIGAZA Tuya WiFi Motion Sensor Stair Light Kit. A convenient main-line cable connects every stair light to one shared line, making installation cleaner, faster and easier than traditional individual wiring.

Automatic Light When You Need It

Two PIR motion sensors detect movement from the top and bottom of your staircase. When movement is detected, all stair lights illuminate together and automatically turn off after the selected delay.

With Tuya WiFi APP control, adjustable brightness, adjustable lighting duration and a daylight sensor, this system combines practical automation with clean modern staircase lighting.

Why Choose This Stair Light Kit?

One Main Line. Much Simpler Installation.

Traditional stair lighting can require separate wiring for every step. This system uses a dedicated main-line cable installed along the side of the staircase.

Each 1-meter COB LED strip connects directly to the corresponding connection point on the main line. This reduces cable clutter and helps create a cleaner installation.

Dual PIR Motion Sensor Control

The kit includes two PIR motion sensors for installation near the top and bottom of the staircase.

When movement is detected, the system automatically turns on the stair lighting. After the configured lighting duration, the lights automatically turn off.

Lighting duration can be adjusted up to 300 seconds to suit different staircase layouts and daily usage habits.

Important Lighting Effect Information

This model turns ALL stair lights on together and turns ALL stair lights off together. It does NOT provide a step-by-step sequential lighting effect. If you require step-by-step illumination, choose the MALIIGAZA STEP-09 stair lighting system instead.

Tuya WiFi APP and Optional Remote Control

The controller can connect to the Tuya APP through WiFi for convenient adjustment and control. An optional remote controller is also available for customers who prefer physical remote operation.

Important: APP and remote control functions are effective only while the PIR-triggered lighting system is active. When the stair light is in its inactive/off state, APP and remote commands cannot be used to control the lighting.

Adjustable Daylight Sensor

A dedicated daylight sensor helps prevent the lights from activating when the surrounding environment is already bright enough.

The light sensitivity can be adjusted according to your installation environment. The daylight sensing function can also be disabled when automatic operation is required regardless of ambient light level.

480 LEDs/m High CRI COB LED Strips

Each stair uses a 1-meter COB LED strip with 480 LEDs per meter. High LED density creates a smooth continuous lighting appearance without the obvious individual light points commonly seen on lower-density LED strips.

3. Measure each stair and cut the COB strip only at the marked 50mm cutting points if shortening is required.
4. Clean and dry the mounting surface before applying the LED strip adhesive backing.
5. Connect each stair LED strip to its corresponding main-line connection point.
6. Carefully confirm positive and negative polarity before powering the system.
7. Connect the PIR sensors and daylight sensor to the controller.
8. Connect the controller to the included 24V transformer power supply.
9. Test motion detection, daylight sensitivity, brightness and lighting duration before completing the installation.

Troubleshooting Guide

Important Notes and Safety Warnings

• Never connect the controller or LED strips directly to AC 220V mains power. The controller must be powered through the supplied DC 24V transformer power supply.
• Check positive and negative polarity carefully when connecting the LED strips to the main-line cable.
• APP and optional remote functions are effective only when the PIR-triggered lighting state is active.
• This model does not provide sequential step-by-step illumination. All stair lights turn on and off together.
• Clean and dry the mounting surface before installing the adhesive-backed COB LED strips.
• The supplied LED strips are IP30 and intended for indoor staircase applications.
• Choose the correct stair quantity before ordering so the main-line cable and LED strip quantity match your staircase.

Frequently Asked Questions

1. Does this stair light turn on step by step?

No. This model turns all connected stair lights on and off simultaneously. For sequential step-by-step lighting, choose the MALIIGAZA STEP-09 system.

2. How many stairs can this system control?

The controller supports configurations from 5 to 30 steps. Select the correct step quantity when ordering.

3. How does the motion sensor stair lighting work?

Two PIR sensors detect movement from the top and bottom of the staircase. When activated, all connected stair lights illuminate together and later turn off automatically.

4. Can I control the stair lights with the Tuya APP?

Yes. The controller supports Tuya WiFi APP control for compatible adjustments while the PIR-triggered lighting system is active.

5. Is a remote controller included?

The remote controller is optional. It is included only when you select a product option that includes the remote.

6. Why can I not control the lights from the APP when they are off?

On this model, APP and remote functions are effective only while the PIR-triggered lighting state is active. They cannot control the system while it is in the inactive/off state.

7. Does the system have a daylight sensor?

Yes. The included daylight sensor can prevent motion activation when the environment is sufficiently bright. Its sensitivity is adjustable and the daylight function can also be disabled.

8. Can I adjust the brightness?

Yes. The brightness of the stair lighting can be adjusted through the controller's supported settings.

9. Can I adjust how long the stair lights stay on?

Yes. The lighting duration is adjustable up to 300 seconds.

10. What type of LED strip is included?

The kit uses 24V COB LED strips with 480 LEDs per meter, CRI 90+, 8mm width and approximately 1000-1100 lumens per meter.

11. Can the COB LED strips be shortened?

Yes. The included COB LED strips can be cut every 50mm at the designated cutting points.

12. Are the LED strips waterproof?

The included COB LED strips are rated IP30 and are intended for indoor use. They should not be treated as waterproof lighting.

13. What color temperatures are available?

You can choose Warm White 3000K, Natural White 4000K or Cold White 6000K according to the available product variants.

14. What voltage does the stair lighting system use?

The LED strips and controller operate on DC 24V through the supplied transformer power supply.

15. Can I connect the controller directly to AC 220V?

No. Never connect the controller or LED strips directly to AC 220V mains power. Always use the supplied transformer power supply.

16. Is the power supply included?

Yes. A transformer power supply is included. The applicable US, EU, AU or UK plug version is allocated according to the destination country.

17. Why is this main-line stair light easier to install?

Instead of separately routing complex wiring for every stair, one main-line cable runs along the staircase and each LED strip connects directly to that line.

18. What should I check if one LED strip does not work?

Check the connection between the strip and main-line cable and confirm that positive and negative polarity are connected correctly.
